Description

Technical Field

[0001] The utility model relates to the technical field of thyroid puncture tools, in particular to a thyroid tissue puncture device. Background Art

[0002] Thyroid disease is a common endocrine system disease in clinical practice, and its diagnosis is of great significance for the treatment of patients. At present, thyroid puncture technology is one of the important means of diagnosing thyroid disease. Thyroid tissue samples are obtained through puncture and pathological examination is performed to clarify the nature of the disease. At present, when performing thyroid puncture, it is generally performed with an existing syringe. The main method is to insert the puncture needle into the part of the patient that needs puncture, and then extract by pulling the piston in the syringe. When pulling the piston, it is difficult to stably control the pulling force, the operation is difficult, and it is difficult to accurately grasp the amount of tissue cyst fluid extracted, which can easily cause more pain to the patient.

[0003] A Chinese patent discloses a thyroid puncture device (authorization publication number CN219763496U). This patented technology controls the amount of fluid extracted from the patient's cystic tissue by rotating the adjustment cap. Compared with the traditional method of directly pulling the piston in the syringe to extract fluid, this method is not only convenient but also easier to control the amount of fluid extracted, reducing the possibility of causing pain to the patient.

[0004] However, it has certain disadvantages: it requires manual rotation of the adjustment cap, which makes the medical staff's fingers easily sore. In addition, the thyroid tissue fluid of some patients is relatively viscous, so that suction requires a large negative pressure, which makes it difficult for medical staff to rotate the adjustment cap with their fingers, and it takes a lot of time. Patients will constantly swallow saliva during the long waiting time, and swallowing saliva will cause the position of the nodule to change, which requires the use of ultrasound to find the nodule position again, further wasting time. Utility Model Content

[0005] The purpose of the present invention is to provide a thyroid tissue puncture device to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The thyroid tissue puncture device includes a sampling tube, the left end of the sampling tube is connected to a connecting tube, the left end of the connecting tube is connected to a puncture needle, the right end of the sampling tube is rotatably connected to a connecting block, and a sampling mechanism is provided inside the sampling tube, a first gear is installed on the outside of the connecting block, an adjustment mechanism is provided on the outside of the sampling tube, and a support frame is installed on the left side of the adjustment mechanism. The lower end of the support frame is threaded with a support bolt, and a control mechanism is installed on the upper surface of the support frame.

[0008] As a further solution of the present invention: the sampling mechanism includes a threaded rod, a fixed block is installed at the right end of the threaded rod, and a blocking block is installed at the left end of the threaded rod, and the interior of the blocking block is movably connected to the fixed rod.

[0009] As a further solution of the present invention: the adjustment mechanism includes a mounting frame, the lower end of the mounting frame is threadedly connected to a mounting bolt, and a motor is installed inside the upper end of the mounting frame, and the output end of the motor is installed with a second gear.

[0010] As a further solution of the present invention: the upper end of the support bolt is in contact with the lower surface of the sampling tube.

[0011] As a further solution of the present invention: the threaded rod passes through and is threadedly connected to the connecting block, the blocking block is slidably connected to the inside of the sampling tube, and the left end of the fixing rod is installed on the inner left surface of the sampling tube.

[0012] As a further solution of the present invention: the mounting bracket is installed on the outside of the sampling tube, the upper end of the mounting bolt is in contact with the lower surface of the sampling tube, and the second gear is meshed with the first gear.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model is provided with an adjustment mechanism, and the start and stop of the motor is controlled by the control mechanism. The motor drives the connecting block to rotate through the engagement of the second gear and the first gear, thereby causing the sampling mechanism to move to the right, so that negative pressure is generated inside the sampling tube, and the tissue fluid at the patient's thyroid nodule is sucked, thereby replacing the manual rotation of the connecting block, saving time and effort, and avoiding the situation that the tissue fluid at the thyroid nodules of some patients is relatively viscous, making it difficult to rotate the connecting block.
